windows neovim cannot add watch variable (error at self.expression[ 'frameId' ] = frame[ 'id' ])

[igorzhilin]

Description

when adding a watch variable in windows nvim, it gives a python error ending with

self.expression[ 'frameId' ] = frame[ 'id' ]
TypeError: 'NoneType' object is not subscriptable

Is it reproducible in vim?

Only broken in Neovim

Works with clean config?

No

Sample project works?

Not reproducible with sample project

Minimal Reproduction

List of steps to reproduce:

1. on Windows 10 OS

2. Install neovim 0.9.5 winget install Neovim.Neovim

3. Install nvim kickstart git clone https://github.com/nvim-lua/kickstart.nvim.git %userprofile%\AppData\Local\nvim\

4. pip3 install pynvim

5. Add plugin 'puremourning/vimspector' to %userprofile%\AppData\Local\nvim\init.lua inside clause require('lazy').setup({:

   {
   "puremourning/vimspector"
   },

6. Open nvim

7. Run :VimspectorInstall debugpy

8. Create .vimspector.json file in current dir:

   {
   "configurations": {
   "Python": {
     "adapter": "debugpy",
     "configuration": {
       "request": "launch",
       "cwd": "${fileDirname}",
       "program": "${file}"
     }
   }
   }
   }

9. Create 'sample.py' file in current dir:

   my_variable = 0
   print(my_variable)

10. :call vimspector#Launch()

11. Click "Add" under vimspector.Variables and enter watch expression: my_variable

12. Get the error

    ...
    self.expression[ 'frameId' ] = frame[ 'id' ]
    TypeError: 'NoneType' object is not subscriptable

Hmmm. Does this also happen in vim? Could you please supply logs?On 10 Jan 2024, at 13:08, igorzhilin @.***> wrote: Description when adding a watch variable in windows nvim, it gives a python error ending with self.expression[ 'frameId' ] = frame[ 'id' ] TypeError: 'NoneType' object is not subscriptable

I need to note, however, that despite the error, python debugging on windows is working. I am able to add a breakpoint, start the debugging, and it correctly displays my_variable in the watches.

So it's not that big of an issue. I'll just keep this information here in case somebody gets the same error with vimspector on Windows.
